Cross-linked polyethylene(XLPE) is widely used as the insulation of power cables due to its good properties. Nevertheless, some inevitable defects like cracks and cavities existing in cables will initiate electrical trees which is one of the main reason leading to the breakdown of cable insulation. Thus, it is necessary to conduct the study on the effects of cavity on the growth of electrical trees...
Cross-linked polyethylene is widely used as the insulation of power cables due to its superior insulation and mechanical properties. Electrical trees is one of the main reasons for the breakdown of cable insulation. In order to explore the growth process and partial discharge characteristics of electrical trees in cross-linked polyethylene, cuboid samples taken from a commercial cable and a needle-plane...
